Specification of Letters Patent.

Application filed March '7, 1906. Serial No. 3%,628.

To all whom it may concern:

Be it known that. I, GUSTAV B. Persona, a subject of the Emperor ofGermany, residing in the city and. county of Philadelphia, in the Stateof Pennsylvania, have invented a certain new and useful Improvement inCondensers, of which the following is a true and exact description,reference being had to the accompanying drawings, which't'orm a partthereof.

My invention relates 'to condensers of the general character'of thecondenser described in the patentto Weiss, reissue 11,591 or March 2nd,1897, in which condenser the steam is condensed generally by a countercurrent mode of operation, but sometimes by a parallel current mode ofoperation, means belng provided for interrupting the vacuum when thecondenser works by parallel currents and thus restoring it to normalcounter current operation.

proved condenser.

The object of my invention is chiefly-to provide improved means forinterrupting the vacuum and restoring the normal counter currentoperation in the apparatus, but I also have in view the generalimprovement of condensers of this kind.

The nature of my improvements will be best understood as described inconnection with the drawings in which they are illus trated, in which-Figure 1 is a side elevation of my im Fig. 2, a sectional elevation onthe line 22 of Fig. 1. Fig. 3, a plan view of the-head of the separationchamber with the top of the air-chamber removed. Fig. d is acrosssectional view through the air chamber taken as on the line H ofFig. 3, showing the lid of the air chamber in place. iii his aperspective view of the perforated imcket, and Fig. 6 is a perspectivevien of the air valve and the parts of the valve operating mechanismdirectly connected therewith. 1

A is the bod otthe condenser, B the steam inlet leading into the bottomthereof, 0 the inlet leadingiu'to the top thereof, D tin-opening forconvenient access to the lower part of the condenser body, E, E thewater baron'ieter wastc pipe connecting with the bottom of the condenserand opening at bottom into a box E having openings as indicated at l) ateach end, saidppenings being provided with l'iinged gates or valves 12*.The construction of the box. and its valves is the same as that of thebox marked 11*, shown in Fig. 2, and hereinafter described. The box issituated in the waste water well I which in my improved'construction isa closed Well provldediwith a take oil pipe F and a cover F throughwhich the water barometer pipes pass.

From the top of the condenser body leads the conduit G, ail-extension Gof which is prolonged into the separation chamber H, as shown in .Fig.2. An air pipe I, leads Patented Feb. l, 1910.,

from the top of this separation chamber to an air pump I. The separationchamber H connects at bottom with a water barometer waste pipe H, whichextends down into the waste water well connecting at bottom with a box Hhaving openings H provided with hinged valves Hf. I

To an elbow G? onthe pipe G I attach the air chamber'J, provided with anair port J, and supporting pivots'at J 2 and J.

K is the air. valve, normally heldseatedon the air port by someyieldingor resilient force, as by 'being supported on the cross bar K ofthe levers K K? pivoted at J,

and provided with a counterweight K.' The valve has also attached to itthe rod L, which is connected with the end of the lever L pivoted in theair box at .J, and connected atan intermediate point with the dependlngrod U, which extends into the separation chamber, where itis attached toa perfo-- rated bucket M, iv indicating the perforation in the bottom ofthe bucket, and M? guide plates secured to the walls of the sepa rationchamber and serving to steady the perforated bucket. A pipe J connectswith the air box J and leads into the head of the condenser chamber, asshown in Fig. 2. v

To return to the detailed construction of the condenser chamber, it willbe. seen that the water'inlet 0 leads into an annular water chamber A inthe top of the condenser, an annular rim A being provided at the top ofthe chamber and formed to direct the overflow of the water inwardlytoward the center of the chamber, where it flows against a conicalbattle plate A, provided with perforations, through which a ortion otthewater is directed inward, whi e another portion tldwing over the bafiieplate is directed outward, as shown, and flows down until it comes-incontact with the annular conical flange or battle plate A also providedwith perforations through which a portion of the water flows downwardwhile the remainder of the water is directed inwardly tothe perforateddish-like battle plate indicated at A A tubular extension A5 extends upfrom the dish A, and a tubular extension A extends upward from the topof the conical baffle plate A, and at the bottom or" the condenserchamber I provide the upwardly converging flange A to insure that thewater shall fall into the upper end of the waste pipe E out of contactwith the sides of the pipe.

By inclosing the waste water well F, I avoid objectionable features ofsimilar condensers owing to the splashing of water and. occasionalebullitions of steam, and by placing the device which covers themechanism for breaking the vacuum in the separation chamber I also avoidthe splashing of water mally in such volume that whatever portion iscaught in the pail M runs freely out of the perforation Mf. Where thewater is heated in the condenser body to a point where it willdpassupward with the air and steam in stea of downward, it rushes into theseparation chamber H, in such volume as to fill the perforated pail M,the weight of which when filled with water is sutlicient to overcome thecounterbalance K and draw the air valve K downward, permitting air toenter the air box through the port J, whence it passes into the ipe Gand also through the pipe J into t e head of the condenser body,breaking the vacuum in the condenser to such a point that the water willno longer pass upward with the steam and thus restoring the condenser tonormal counter current operation.

The'bafi le plate system of the condenser body has already beensutliciently described and is clearly indicated by the lines indicatingthe How of water in the drawing, Fig. 2. Having now described myinvention, what I claim as new and desire to secure by Letters Patentis:

1. In a condenser of the character described adapted to operate eitheras a parallel current or counter current condenser, the combination withthe condensing chamber and the conduit through which the water passesfrom the condensing chamber when the condenser is working as a parallelcurrent condenser, of means for temporarily ceases breaking the vacuumin the condenser, and an actuating device for said means comprising aperforated pail situated in said con-- dint. above the level to whichwater accumulates therein, and normally held in a fixed non-operativeposition by a yielding force, said pail being arranged. to be urged inthe same direction out of said non-(normative po sition by the direct.impact against the pail of the water passing through said conduit and bythe weight oi the water accumulating in said pail.
